Problems solved by technology

[0012] Currently, the fume hoods used in chemical laboratories are limited by the way of air intake and exhaust. For granular dust, only a large air intake can be used for exhaust. The air in the hood is disturbed greatly, which will affect or destroy the experimental results, and can not effectively remove the dust.

Embodiment 1

[0040] Please refer to figure 1 , figure 2 , image 3 As shown, a device for purifying pollutants in an operating area includes a main body 1, a vent 2 is provided on the front side of the main body 1, and a vent window 21 capable of controlling the opening and closing of the vent 2 is provided on the vent 2. The ventilation window 21 can be opened or closed by sliding, and the size of the ventilation opening 2 can be controlled by sliding. The sliding opening manner of the ventilation window 21 includes but not limited to horizontal sliding, vertical sliding, rotating sliding and the like.

[0041]The main body 1 is provided with a ventilation cavity 4, and the ventilation cavity 4 communicates with the ventilation interface. The ventilation cavity 4 is divided into a top ventilation cavity 41 and a vertical surface ventilation cavity 42 . The top ventilation chamber 41 is composed of a top solid wall plate 11 and a top plate 412, on which a variable-gap damper 411 is ar...

Embodiment 2

[0052] Such as Figure 4 As shown, the device for purifying pollutants in the operating area is connected in parallel by multiple devices for purifying pollutants in the operating area, sharing a set of ventilation equipment. Other structures are with embodiment 1.

Abstract

The invention relates to a device for purifying pollutants in an operating area. The device for purifying the pollutants in the operating area is characterized in that the device comprises a body, andthe body is provided with a ventilating port; the body is internally provided with a ventilating cavity, and the ventilating cavity comprises a top ventilating cavity body and a vertical face ventilating cavity body; the top ventilating cavity body is composed of a top solid wall plate and a top plate; a gap-variable air door is arranged on the top plate; and the vertical face ventilating cavitybody is composed of a vertical face solid wall plate and a vertical plate, and the vertical plate is provided with a ventilating hole. The device for purifying the pollutants in the operating area provides a new air exhaust mode and an air volume adjusting mode for a fume cupboard, and under the condition that air disturbance in the cupboard is controlled, the granular dust pollutants produced inan experiment are effectively removed.

Description

technical field [0001] The invention relates to a device for purifying pollutants in the operating area, which is used to prevent the leakage of toxic and harmful gases generated in the experiment process, and in particular to a chemical laboratory fume hood that can effectively remove the granular dust generated in the experiment, so as to avoid Contaminate the environment and cause harm to laboratory personnel. Background technique [0002] In the chemical laboratory, various harmful gases, odors, moisture, and flammable, explosive, and corrosive substances are produced during experimental operations. In order to protect the safety of users and prevent the pollutants in the experiment from spreading to the laboratory, in Use a fume hood near sources of contamination. The main function of the fume hood is to exhaust the air, so as to solve the impact of the reaction of toxic and pathogenic vapors, gases and particles (smoke, soot, dust and aerosol) or the reaction of a lar...
